Question

Are cilia found in Bacteria?

Answer 1

The purpose of cilia is to transfer water relative to the cell in a regular manner. This mechanism can either cause the cell to move through the water, as many single-celled organisms do, or it can cause water and its contents to move across the cell's surface.

Complete answer:
In bacterial cells, cilia do not exist. The cilium, also known as Cilia, are small hair-like projections that protrude from the cell wall. They are only found on eukaryotic cells and are primarily engaged in motility. Flagella are seen in prokaryotes, however they are fundamentally distinct from eukaryotic flagella.
Flagella can be seen on prokaryotes in multiples. In both prokaryotes and eukaryotes, they have the same function (moving an entire cell). Cilia don't exist in prokaryotes. Cilia are hair-like appendages that protrude from a live cell's surface. Flagella are long, threadlike extensions on a live cell's surface. It can be found all throughout the cell surface. The axoneme, a rod inside cilia and flagella made up of nine microtubule doublets organised in a circle with a central pair of microtubules (but not always), generates beats. The cilium (from Latin 'eyelash'; plural cilia) is a slender protuberance that extends from the much larger cell body of eukaryotic cells.
Cilia are divided into two types: motile and non-motile. Primary cilia are non-motile cilia that function as sensory organelles. A single non-motile main cilium exists in most mammalian cell types, which serves as a cellular antenna.

Note:-
Cilia: Fine hairlike extensions from specific cells, such as those in the respiratory tract, that sweep in unison and aid in the removal of fluids and particulates. The rhythmical motion of cilia is used by several single-celled organisms for mobility.
